Analysis of Influenza B Virus by Real-Time PCR Method (CAT#: STEM-MB-3490-LGZ)

Introduction

Influenza B virus (IBV) is a segmented negative-strand RNA virus, which often causes local outbreak or seasonal epidemic along with influenza A virus (IAV) in the world. It is pathogenic to children, teenagers and elderly people and has a higher mortality rate in children and adolescents, so it poses a serious threat to public health and health.<br />A real-time polymerase chain reaction (real-time PCR, or qPCR) is a laboratory technique of molecular biology based on the polymerase chain reaction(PCR). It monitors the amplification of a targeted DNA molecule during the PCR(i.e.,in real time), not at its end, as in conventional PCR.<br />Two common methods for the detection of PCR products in real-time PCR are(1)non-specific fluorescent dyes that intercalate with any double-stranded DNA and (2)sequence-specific DNA probes consisting of oligonucleotides that are labelled with a fluorescent reporter, which permits detection only after hybridization of the probe with its complementary sequence.
